Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent accidental airbag deployment.

2. Inspect Wiring and Connectors

Tools Required: Socket set, multimeter, electrical contact cleaner.
Remove the passenger seat by unscrewing the bolts with a socket wrench.
Carefully lift the seat and inspect the wiring harness for frayed wires or loose connections.
If any connectors are corroded, clean them with electrical contact cleaner and a brush.
Ensure each connector is firmly seated and locked in place.

3. Replace Passenger Presence Sensor (if necessary)

Tools Required: Socket set, ratchet, torque wrench.
If the sensor is faulty, disconnect the wiring harness from the sensor located under the seat.
Remove the sensor by unbolting it from the seat frame.
Install the new sensor, tightening bolts to the manufacturer's specified torque (usually around 10-15 ft-lbs, check your repair manual).
Reconnect the wiring harness securely.

4. Reassemble and Test

Reinstall the passenger seat and secure it with bolts.
Reconnect the negative battery terminal.
Start the vehicle and check for the airbag warning light and any reoccurring codes.
